Answer:
5.1 cm²
Step-by-step explanation:
The area of a segment is given by the formula ...
A = 1/2r²(α -sin(α)) . . . . . where α is the central angle in radians
For this segment, its area is ...
A = 1/2(6 cm)²(7π/18 -sin(70°)) ≈ 5.077 cm²
The area of the segment is about 5.1 square centimeters.
_____
The angle is converted to radians by multiplying by π/180°. Then a 70° angle is π(70°/180°) = 7π/18 radians.
Answer:
function
Step-by-step explanation:
Wait i want to say a median cause a median is connected to a midpoint ad a midpoint divides a segment into 2 congruent segment, or i guess you cant use a reflexive property, i feel like i'm saying nonesense
Answer:
Rate of change is increase of 51 followers per year.
Step-by-step explanation:
Given:
Number of followers in 2012 = 74
Number of followers in 2015 = 227
Therefore, increase in followers = 227 - 74 = 153
Duration for the change = 2015 - 2012 = 3 years
Rate of change of followers is given as:
Therefore, rate of change is increase of 51 followers per year.
